TO ALL WHGM IT MAYCONGERN:

i Be it known 'that I, GEORGE F. JOHNSQN, of Marshall, inthe county of Henry, and State of Iowa, have invented a new and useful Improvement in Corn-Shelling Machine; Aand I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had t-o the accompanying drawings, forming part of this specication.

The nature of my inventionrelates toimprovements in machines `for shelling corn, whereby it is designed to provide a simple,cheap, `and effective machine for that purpose; and it consists 'in a rotary wheel provided 4with a centralopening, in which is provided a series of hooked shellers, having gauges which press upon the cob, to prevent the shellers from scraping the cob too deeply, thesaid shellers beingprovilded, also, with radial stocks, which slide in corresponding grooves'in the rotary Wheel, and surroundedby a spring, which constantly bears them-towards the centre of' the said rotary wheel. A set of lfeeding-rollers is also provided' for grasping the cob after aportion of. corn on one end of `the-'ear has been-shelled ott, and` drawing it through the sheller, the whole being actuated from a hand-crank, as will be more fully described onreiference to the accompanying drawings, whereinp v i l Figure 1 represents a plan of a portion of the machine and a` horizontal section of another portion of the same.

Figure 2, an end elevation, with a. part broken away, and

Figure 3 the same end elevation with the feed-rollers removed.

Figure 4 is a perspective view of one ot' theshellng-lips, detached.

Similar letters of reference indicate corresponding parts. l d v A represents a platform provided with a. right-angled upright,j B and B. G represents a wheel provided with a gear-rim, Ci, andV alarge central opening, C2, and-which is arranged torevolve in a circular opening in the upright, B, and is maintained in that position bythe edge of the plate B2, which takes into the annular groove a in the wheel. The said wheel C is provided with four or any other suitable number of hooked shellers,

b Il and b, providedwith Shanks, which work in radial grooves l in the said wheel C, and which are constantly borne inward towards tho centre by the elastic band Said Ishellers are kept in position by means of a confining-disk, .rigidly attached tothe exterior faceof wheel C, and moving with it.

The `hooked shellers arc provided with'the curved plates e e and e1 el, facing inward, which are pressed againstthe cob, after the corn has been rcmoved, by the spring D. The plates e e are made shorter than'the plates e el, and prevent the latter from closing up towards the centre'by the action of' the spring beyond the point which is presumed to be the limit for the smallest cob. The plates ee are limited in their movement towards the centre by the curved plates e2 e2' striking against the ends of the plates el el. The plates e2 also serve to centre the ear before it is taken hold of by the shellers:

' E E representa pairof'fecd-rollers, which rec'eivethe end of the cob as it passes through the shellers and protrudcs far enough to be taken hold of by them,to draw it through and deliver it to the floor. Thejournals ofsthe rollers work in slotted bearings, which allow them to separate, to agree with the'various sizes of cobs, and are drawn .together by elasticbandsff at each end. The wheel C receives motion from the wheel F on the driving-shaft S, and therollers E receive motion from' a pinion, G, also on the driving-shaft, through suitable intermediate wheels. i i i In working the machine, the operator turns the crank with one hand, and with the other presents the ear, point irstjtoA the shellers, holding lit and forcing it through the' shellers until a suicient amount has been shelled, and' it has been pushed4 through far-enough for the drawing-rollers to take sutlicient hold of the cob to hold it against the action of theshellers and ldraw it,`when he lets go his hold on it and4 picks up another ear, and holds it in readiness to present to the shellers as soon as the former has been drawn through. As the point'oi an car is presented to the shellers, thc points are brought into contact with the same near the roots of Y the kernel, and by reason of tho rotary motion of the former, act upon the car in a manner similar to the action of a. rotary saw, severing the kernels from the cob in a. very expeditious manner. The plates e e and e e1 pre-A vent the shellcrs from being caused to cut into the cob by reason of the inward pressure of the spring D, and also serve to centre the ear. One roller, E, is' provided with pins for drawing the cob through, andthe other roller is provided with circular projecting ribs, to prevent the shellers from turning the ear around with then-.1.

I claim as new, and desire to secure by Letters Patent- 1. The radially-expanding sheliers, provided with the curved plates e e and e el, in combination with the Wheel C and spring D, substantiallya-s and for .the purpose described.

2. The arrangement, with relition to the drawing-rollers E E :md she11ing-\vhee1 C, having the toothed rim C1 of the drive-sbaft S, mein wheel F, pinion G, and eonnectinggearing, as herein shown and described, upon the frame A B BLfor the purpose specified.
